Designed for large virtualized data centers and cloud networks the Arista 7500 Series modular switches are the industry’s highest performance data center switches, available in a compact 7RU (4-slot) or 11RU (8-slot) they combine scalable L2 and L3 resources with advanced features for network monitoring, precision timing, network virtualization to deliver scalable and deterministic network performance for mission critical data centers, enterprise and HPC environments.

The Arista 7500E is the second generation of the 7500 Series and delivers seamless upgrades ensuring investment protection of first generation fabrics, line cards and common equipment while setting a new standard for performance, density, reliability, and power eﬃciency. The Arista 7500E Series oﬀers over 30Tbps of total capacity for 1,152 ports of 10GbE or 288 ports of 40GbE and support for 96 ports of wire-speed 100GbE with a broad choice of interface types that support flexible combinations of 10G, 40G and 100G modes on a single port.

With front-to-rear airflow, redundant and hot swappable supervisor, power, fabric and cooling modules the system is purpose built for data centers. The 7500E Series is energy eﬃcient with typical power consumption of under 4 watts per port for a fully loaded chassis. All of these attributes make the Arista 7500E an ideal platform for building reliable, low latency, resilient and highly scalable data center networks.

Arista EOS
All Arista products including the 7500E Series runs the same Arista EOS software, binary image simplifying network administration with a single standard across all switches. Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service-software updates and self-healing resiliency together with stateful switchover without the loss of data plane forwarding.

Arista EOS enables advanced monitoring and automation capabilities such as Zero Touch Provisioning, LANZ, VM Tracer and Linux based tools to be run natively on the switch.
